Installing the RTN 380e
4
Installing the RTN 380e at 2x(1+0) Aggregation Sites
Retain removed caps for future use.
1.
Cover unused ports with caps/PG covers.
2.
Before installing the RTN 380e, remove the protective cover and film on the antenna port. Otherwise, the signal transmission will be affected.
3.
Different methods can be used to change the polarization direction of antennas. If the method provided in this document is not suitable for the type of antenna you have, use the method provided in the installation manual delivered with your antennas.
4.
The polarization direction of antennas is vertical by default. If the planned polarization direction is horizontal, change the polarization direction to horizontal.
5.
If an antenna with a diameter of 0.2 m, 0.3 m or 0.6 m is used in a direct mount scenario, you may install the RTN 380e on the antenna and then hoist them both into position on the tower.
6.
Before installing a cable, bind the cable section that links the cable connector to the pole. This will protect the cable connector from damage. Be sure that the length of cable running from the binding point to the RTN 380e is sufficient to attach the cable connector to
the Ethernet service port on the RTN 380e.
Installation procedure
1
Follow the antenna use instructions to
install the antenna.
2
Optional
: Change the polarization direction
of the antenna to horizontal.
Apply petroleum jelly around the exterior
3
side of the feed.
4
Install the RTN 380e on the antenna.
Install the PGND cable of the
5
RTN 380e.
•Install a GE cascade fiber.
6
•Moistureproof the fiber.
7
Install a GE cable.
•Install the GE cable.
• Select a ground point for the GE cable.
• Install the ground clip.
• Lay out the GE cable.
•Attach a yellow outdoor label to the
cable according to the plan.
8
Install a PI and install cables on the PI.
• Install a PI on an auxiliary mounting bracket.
• Install the bracket in a 19-inch cabinet, ETSI
cabinet or outdoor cabinet, or install the
bracket on a wall.
• Install cables on the PI.
9
Waterproof the ground clip and do anti-
corrosion treatment for GE ports.
Check the installation.

In this example, the GE(o) link and COMBO
link between two back-to-back RTN 380es
form a LAG of cascade links. Actually, either of
the links can form an unprotected cascade link.
